Question : Problem: Why do all computers on my network default to Google FRANCE????

Alright, here's my setup:

Time Warner Cable, Northeast Ohio
Dumb modem (I don't recall the brand)
Apple Airport Express (802.11G model)
Apple iMac
Apple Macbook

The two Mac systems default to Google in French whenever I search, regardless of which browser I use. My sister-in-law brings over her old Sony notebook running XP SP2 and Google Chrome defaults to French as well. I bring home my work Dell Latitude D600 and it too defaults to Google in French regardless of if I use IE, Chrome or Firefox.

I've pulled the power on the network equipment for 5 minutes.

All language settings are set to English. French is not even in the list.
